FIRE-BOX FOR FORGES.

SPECIFICATION forming part of Letters Patent No. 303,487, dated August12, 1884.

Application filed January 11, 1884. (No model.)

To all whom it may concern.-

Be it known that I, CARL F. BoYENs, of Harrisburg, in the county ofDauphin and State of Pennsylvania, have invented certain Improvements inForges and I hereby declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making a part of this specification, in which--- I Figure l isa side elevation of a forge with my improvements attached. Fig. 2 is aplan view of the same. Fig. 8 is a vertical longi tudinal sectional viewon the line a a of Fig. 2.

My invention relates to forges used byblacksmiths and others, and hasfor its object to increase the wearing capacity of the fire box toprevent the stickingof the cinders and economize fuel.

To this end my invention consists in a forge provided with a hollowfire-box, in which a circulation of water-is induced from a tank orother convenient receptacle, as will be hereinafter fully described, andspecifically pointed out in the claim.

In order that those skilled in the art may make and use my invention, Iwill proceed to describe the manner in which I have carried it out.

In the said drawings, A is the firebox of a forge, composed of the wallsa 12, forming a chamber, (1, which surrounds the fire-opening e, andlies below the perforated plate f to a plane 3 ust above theingress-point of the tuyere g. A water-tank, B, is placed in someconvenient location near the forge, and is provided with a water-supp] ypipe, 0, which connects it with the chamber d at i,t0 carry water intoandfill said chamber. The pipe 0 isprovided with a eheck-valve, k, asshown, for a 0' purpose hereinafter described. Another pipe,

cock on on the ingress water-pipe O the water flows into the chamber (Z,thereby keeping the innerwall,b,comparatively cool. Assoonastheforge-fire heats the water sufficiently to make a pressure from thesteam, some ofthe water in the chamber is forced out through pipe 1)into the tank, the check-valve Ic preventing the water'passing backthrough pipe 0. As soon as the pressure is relieved by this escape ofwater, water again flows in through pipe'O to take the place of thatwhich escaped through pipe D. In this way a constant circulation ofwater is kept up and the walls of the fire-box prevented from becominghighly heated.

It is evident that this fire-box may be made adjustable for all kinds ofblacksmiths forges, and that more than one firebox can be supplied fromthe same water-tank.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

In a blacksmiths forge, a continuous water- I chamber beneath the hearthand fire-box and surrounding the tuyere-box, formed by walls a b,incombination with pipe D, pipe 0, provided with a cheek-valve, 7c, tankB, and tuyere 9, all constructed, arranged, and operated as de scribed.
